Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of display, and in particular, to a display module and a display device. BACKGROUND

[0002] In the existing display module, a super clean foam (SCF) composite film is usually arranged on one side of the backlight side of the display panel, and the SCF composite film includes an adhesive layer and a buffer heat dissipation layer. The SCF composite film can buffer the stress acting on the display panel and dissipate the heat generated during the operation of the display panel, thereby protecting the display panel to a certain extent.

[0003] However, the adhesive layer in the SCF composite film is prone to overflow to the edge of the display panel, causing static electricity to accumulate at the position and unable to be released in time, thereby increasing the risk of performance degradation of the display module. SUMMARY

[0004] To solve the above technical problems or at least partially solve the above technical problems, the present disclosure provides a display module and a display device.

[0005] The present disclosure provides a display module, comprising: a display panel; a support film located on the backlight side of the display panel; a composite film located on the side of the support film away from the display panel, the composite film comprising a first adhesive layer and a buffer heat dissipation layer, the first adhesive layer being located between the support film and the buffer heat dissipation layer; the side of the support film away from the display panel is provided with a groove, and the groove penetrates part of the support film in the direction of the plane on which the display panel is located.

[0006] The present disclosure also provides a display device comprising the above display module.

[0007] The technical solutions provided by the present disclosure have the following advantages compared with the prior art:

[0008] In the display module provided by the present disclosure, the side of the support film away from the display panel is provided with a groove, and the groove penetrates part of the support film in the direction of the plane on which the display panel is located, that is, the groove in the support film is recessed in the direction away from the first adhesive layer. Therefore, when the first adhesive layer is subjected to pressure, the side wall of the groove will block the overflow of the first adhesive layer, so that the groove can effectively alleviate the overflow of the first adhesive layer, thereby reducing the risk of overflow of the first adhesive layer to the edge of the display panel, reducing the risk of static electricity accumulating at the edge of the display panel, thereby reducing the risk of static electricity entering the inside of the display panel, and further reducing the risk of performance degradation of the display module.

[0009] Correspondingly, the display device provided by the present disclosure also has the above technical effects. BRIEF DESCRIPTION OF DRAWINGS

Of course, in other embodiments of the present disclosure, the material of the buffer and heat dissipation layer 32 can also adopt other materials, which will not be described here in detail.

[0033] When the composite film 30 is attached to the side of the support film 20 away from the display panel 10, the first adhesive layer 31 has the risk of overflowing under pressure. The side of the support film 20 away from the display panel 10 is provided with a groove 40. In the direction of the plane on which the display panel 10 is located, the groove 40 penetrates part of the support film 20, that is, the groove 40 in the support film 20 is recessed in the direction away from the first adhesive layer 31. Therefore, when the first adhesive layer 31 is under pressure, the side wall of the groove 40 will block the overflow of the first adhesive layer 31, so that the groove 40 can effectively alleviate the overflow of the first adhesive layer 31, thereby reducing the risk of the first adhesive layer 31 overflowing to the edge of the display panel 10, reducing the risk of static electricity gathering at the edge of the display panel 10, thereby reducing the risk of static electricity entering the inside of the display panel 10, and further reducing the risk of performance degradation of the display module.

[0036] Specifically, the groove 40 includes a first groove 41, and a vertical projection of the first groove 41 on a plane where the display panel 10 is located at least partially surrounds a vertical projection of the buffer heat dissipation layer 32 on the plane where the display panel 10 is located, that is, the first groove 41 is arranged between the edge of the buffer heat dissipation layer 32 and the display panel 10, so that when the first adhesive layer 31 is subjected to pressure overflow, the overflowed part will preferentially fill into the first groove 41, and the side wall of the first groove 41 can further block the first adhesive layer 31 from continuing to overflow, that is, the first groove 41 can effectively block the overflow of the first adhesive layer 31, thereby reducing the risk of the first adhesive layer 31 overflowing to the edge of the display panel 10, reducing the risk of static electricity gathering at the edge of the display panel 10, thereby reducing the risk of static electricity entering the inside of the display panel 10, and further reducing the risk of the working performance of the display module being reduced.

[0037] It should be noted that, Figure 1 In the embodiment, the vertical projection of the first groove 41 on the plane where the display panel 10 is located is shown as surrounding the vertical projection of the buffer heat dissipation layer 32 on the plane where the display panel 10 is located. In other embodiments of the present disclosure, the vertical projection of the first groove 41 on the plane where the display panel 10 is located can also only partially surround the vertical projection of the buffer heat dissipation layer 32 on the plane where the display panel 10 is located. The specific setting range of the first groove 41 can be set according to actual needs, and the present disclosure will not be repeated here.

Optionally, the material of the support layer 21 can be PET plastic, and the material of the second adhesive layer 22 can be pressure sensitive adhesive. Of course, in other embodiments of the present disclosure, the material of the support film 20 can also use other materials, which will not be repeated here.

[0042] In the direction along the plane where the display panel 10 is located, the first groove 41 at least penetrates part of the support layer 21, that is, the first groove 41 is formed on the support layer 21, so that when the first adhesive layer 31 is subjected to pressure overflow, the overflowed part will preferentially fill into the first groove 41, and the side wall of the first groove 41 can further block the first adhesive layer 31 from continuing to overflow, that is, the first groove 41 can effectively block the overflow of the first adhesive layer 31, thereby reducing the risk of the first adhesive layer 31 overflowing to the edge of the display panel 10, reducing the risk of static electricity gathering at the edge of the display panel 10, thereby reducing the risk of static electricity entering the inside of the display panel 10, and further reducing the risk of the working performance of the display module being reduced.

[0043] And the first groove 41 can be directly formed on the support layer 21 by laser Hatching process, which is simple in process and is conducive to improving production efficiency and reducing production cost.

[0045] Specifically, in the direction along the plane where the display panel 10 is located, the first groove 41 penetrates the support layer 21, and the first groove 41 penetrates part of the second adhesive layer 22, so that in the direction along the plane where the display panel 10 is located, the depth of the first groove 41 is higher, that is, the accommodation space of the first groove 41 is larger, so that when the first adhesive layer 31 is subjected to pressure overflow, the first groove 41 can accommodate more overflowed parts, and the side wall of the first groove 41 can further block the first adhesive layer 31 from continuing to overflow, that is, the first groove 41 can effectively block the overflow of the first adhesive layer 31, thereby reducing the risk of the first adhesive layer 31 overflowing to the edge of the display panel 10, reducing the risk of static electricity gathering at the edge of the display panel 10, thereby reducing the risk of static electricity entering the inside of the display panel 10, and further reducing the risk of the working performance of the display module being reduced.

[0046] Meanwhile, when the first adhesive layer 31 is subjected to pressure overflow, the overflowed part will preferentially fill into the part of the first groove 41 located in the second adhesive layer 22, so that the overflowed part will be bonded with the second adhesive layer 22, which is beneficial to improve the adhesion of the first adhesive layer 31, effectively reduce the occurrence of delamination, ensure the close combination of each layer of material, and improve the durability and reliability of the product.

[0050] Meanwhile, the arrangement of the second groove 42 does not affect the spacing between the buffer heat dissipation layer 32 and the edge of the display panel 10, which is beneficial to reduce the spacing between the buffer heat dissipation layer 32 and the edge of the display panel 10, thereby being beneficial to increase the arrangement area of the buffer heat dissipation layer 32, thereby improving the protection effect on the display panel 10, and being beneficial to shorten the diffusion path of static electricity from the edge of the display panel 10 to the copper foil in the buffer heat dissipation layer 32, being beneficial to the static electricity at the edge of the display panel 10 being led out to the copper foil in the buffer heat dissipation layer 32 and then being released through the copper foil, thereby reducing the risk of static electricity entering the inside of the display panel 10, and further reducing the risk of the working performance of the display module being reduced.
